Central heating working ok but hot water temperature not regulating. Water heats up until the over temp thermostat cuts in. Water and heating thermistors both check out ok suspect it maybe the Modureg control valve or the control PCB.
What voltege does the control valve work on? as I can put a seperate variable supply to this, to see if it is working ok or not.
If anyone can help with this inf it will be much appreciated.
Thanks B Wilkes
